HVAC Senior Design Engineer; On-site

Job Overview

Sr. Design Engineer is a hands‑on, self‑directed role supporting a small manufacturing team focused on residential and commercial HVAC products. The position reports to the Director of Engineering and independently owns complex engineering assignments across new product development, sustaining, and value engineering, executing each task through completion with minimal supervision. The role requires the ability to work across disciplines, solve multi‑variable technical problems, and deliver results that directly impact product performance, cost, and manufacturability.

This is an onsite role based at the Aspen manufacturing facility in Humble, TX.

• Own the design and development of HVAC product subsystems and components, executing prototype builds, design verification testing, and production handoff with minimal oversight.
• Perform engineering CAD and analysis using Solid Works, FEA, vapor cycle and coil design tools, and in‑house analytical models to validate thermal, structural, and airside performance.
• Create, maintain, and release accurate bills of material (BOMs) and engineering documentation, ensuring revision control and configuration accuracy throughout the product lifecycle.
• Coordinate technical development—including scope, testing, simulations, and proof‑of‑concept builds—with management, engineering, and operations.
• Support production and factory operations by troubleshooting manufacturing issues and implementing design‑for‑manufacturing (DFM) improvements on new and legacy products.
• Manage engineering change notices (ECNs), BOM updates, and supplier qualification testing for sustaining activities including material substitutions, supplier changes, and field issue resolution.
• Contribute to cost‑reduction and value engineering initiatives: support should‑cost analysis, teardowns, competitive benchmarking, and assist in qualifying alternative components through testing and supplier coordination.
• Plan and execute lab testing for performance verification, reliability validation, and component qualification; analyze results and document findings with recommended design actions.
• Interface with sales, supply chain, and manufacturing to ensure customer and production requirements are met; support complex application requests and develop custom configurations as directed.
• Maintain working familiarity with applicable AHRI, UL, ASHRAE, and DOE standards for HVAC products; coordinate with regulatory agencies and testing labs as needed.
• Read and interpret electrical schematics and wiring diagrams; specify electrical components and coordinate with controls resources on system integration.
• Use structured problem‑solving methods (root cause analysis, corrective action) to resolve recurring production and field issues.

• Bachelor’s degree in Mechanical, Electrical, Industrial, or equivalent engineering discipline.
• Five years of hands‑on engineering experience in HVAC product development, manufacturing engineering, or related roles.
• Proficiency in Solid Works 3D CAD modeling and engineering analysis.
• Demonstrated experience with engineering simulation tools (FEA, coil/heat exchanger design software, or vapor cycle modeling).
• Practical knowledge of manufacturing processes relevant to HVAC product fabrication (brazing, tube expansion, sheet metal forming, assembly).
• Experience planning and conducting lab testing for product performance and reliability verification.
• Working ability to read and interpret electrical schematics and wiring diagrams.
• HVAC product experience in a manufacturing environment.

• Experience with CFD analysis platforms.
• Engineering background spanning more than one discipline (NPD, sustaining, applications, or value engineering).
• Familiarity with AHRI certification processes, UL/ETL safety standards, and DOE efficiency test procedures.
• ERP system experience (Infor, SAP, or similar) for BOM and routing management.

• Self‑directed and able to independently execute complex engineering tasks with minimal supervision.
• Strong analytical and problem‑solving skills—root cause analysis with a solution‑oriented mindset.
• Effectiv…
